Titration experiment: Determination of the acid content of vinegar. 25.00 mL of vinegar with a 5% concentration of acetic acid is combined with distilled water to prepare a dilute vinegar solution of 250.00 mL. The burette is filled with a standardised NaOH solution with a molarity of 0.09979 M. 25.00 mL of diluted vinegar is pipetted into a conical flask, and phelphthalein indicator is added to it. The volume of NaOH that needed to be added in order for the...
